BEVERAGE-MAKING DEVICE.

Patented April 9, 1907.

Application filed July 14, 1906- Serial No. 326,264.

' Connecticut, have invented a certain new and useful Beverage-Making Device, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use.

the same, reference being had to the accoinpanying drawings, forming part of this specification.

This invention relates to a beverage-preparing device, and particularly to the class of utensils used for the purpose of making coffee. One of the objects of the invention is to provide an efficient means for impregnating a liquid with the aromatic and other desirable properties of the material-fi'om which the beverage is to be made.

In the class of devices known as coffeemachines or *cofl'ee-percolators the generic features include some means for causin a flow or spray of mixture to drip or to be fed over the material from which the beverage is to be made, so that the, material which 1s in the peroolator or receptacle above the beverage-retaining receptacle may be thoroughly acted upon and its ood qualities be associated with theliquirI.

It is the purpose of my invention to im prove this class of devices, and I have illustratedone embodiment of my invention in the accompanying drawings, in which-.-

Figure 1 is a vertical longitudinal sectional view through it coffee-machine constructed in accordance with my invention; and Fig. 2

is a view in plan of the interior of the second-.

ary chamber carried by the base which assists in forming the heating-chamber of the machine. v

In carrying out my invention I may employ a liquid-receptacle 1, of any referred form; but this liquid-receptacle w' l preferably have an ofisettim part 2 at its bottom to receive the removable base 3, to be more fully described hereinafter.

Within the receptacle 1 may be placed a holder or e'rcolat or 4 to receive cofl'ee or other suitable material, and said holder may consist in part, at least, of some reticulated material to provide openings 5', throughwhich the liquid may drip or otherwise pass into the receptacle 1. The upstanding tube 6, carried by the holder 4, is to be fed through the port 7 ,through which the heated water may pass, and this water may be deflected in a spray by coming in contact with the baffle or hood 8, carried by the tube or sleeve 6. The holder 4 may be closed by a cover 9, and this cover maybe conveniently made of suit able transparent materialas, for example, glass-to provide for an inspection of the discharge end ofthe tube 8. The base 3 may be of such conformation as to fit in the recess 2, and the bottom of said base 3 may be concave to provide for a heating-chamber 10. If desirable, this heating-chamber may be insulated from the liquid in the receptacle 1 by .providing a wall 11, approximately parallel with the base, to form an air-space 12, al-

though this double-walled space may be found not to be desirable under all conditions. 7 i

. Above the chamber 10 is a secondary chamber, (designated by the reference-numeral 13,) and this secondary chamber is illustrated. in the drawings as having a floor 14, with an upstanding threaded flange and a plurality of concentric flan es 16 and 17,.respectively.- The floor 14 0% the chamber 13 is provided with a plurality of openings 18. (See Fig. 2.) The chamber 13' is provided with a cap 19, having an annular flange 20 depenfling therefrom and alternating with the flanges 16 and 17, and this flange 20 is concentric with the tube 7, which projects from said cap 19. By reference to Fig. 1. it will be seen that the flange 17 surrounds a discharge opening or port 21, through which communication may be had with the heating-chamber 10, and it will also be observed that the port 21 and the ort 7 are in alinement with each other and t atthe flange 17 terminates short of the inlet portion of the ort or tube 7,

which latterport is preferab y flared or bell.

is trap forme y these alternately-arranged ba es 1e heating-chamber 10.

cd within the tortuous passaes or flanges. Therefore it will follow that if a proper quantity of liquid is forced in the recept acle 1 enough liquid will enter the chamber 10 to fill it. As the bottom of the chamber 10 will be placed adjacent to the source of heat, only that portion of the liquid in the chamber 10 willbecome heated. As the liquid becomes heated it will have a tendency to rise, and as a liquid seal will be formed between the baflles in the secondary chamber the heated liquid will pass through the tube' or port 7 and become distributed over the material in the holder 4. As soon as pressure is relieved within the port 21 and adjacent to it the liquid seal will bedestroyed and a fresh supply of liquid will be permitted to pass through the openings 18 along the tortuous passage formed by the baflies, and thus through the port 2] into the chamber 10. As soon as the second supply is heated it will pass through the tube 7 in the'manner heretofo're described, so that the intermittent filling and discharging of the heating-chamber 10 will continue so long as heat is applied to the bottom of the chamber 10 and so long as there is suflicient liquid in the receptacle The successive passing of the liquid over the *material in the holder 4 will be effective in causing the liquid to be impregnated with the aromatic properties of the material therein and of causing the liquid to partake of any of the properties adapted to be given oil by said material, and after the process has proceeded to a suitable degree the liquid may be poured off through the spout 22. It will be observed that the same port 21 which serves as the exhaust-port from the chamber 10 serves as an inlet-port for said chamber and that said port becomes alternately the inlet and outlet port and that the liquid seal is alternately effected and destroyed during the operation of the machine.

While I have described and illustrated what appears to me to be the best form of my invention, I would have it understood that I do not limit myself to the exact details of construction, but reserve the right to make such changes and alterations as may suggest themselves from time to time without departing from the spirit or subject-matter of the invention as recited in the accompanying claims.

WVhat I claim is'- 1. The combination with two chambers,v

one of which is .a heating-chamber and the other a feeding-chamber, alining ports in communication with said chambers, the feeding-chamber having openings adapted to communicate with the source of liquid-supply,

.and baffles Within the feeding-chamber to mitting one'of said chambers to communicate with the other, the feeding-chamber being adapted to communicate with a source of liquid-supply, a baflie within the feeding-chamber to trap the feed liquid and prevent the escape of the liquid from the heating-chamber back through the feeding-chamber, and a discharge-port in communication with the heatingchamber. I

3. The combination with a heating-chamber having a discharge-port and a source of liquid-supply tor the heating-chamber, of means for permitting liquid from the source of supply to enter said heating-chamber and for preventing the heated liquid from passing bac into the source of liquid-supply, said means providing a liquid seal during the passage of the liquid from the heating-chamber through the discharge-port.

4. The combination with a heating-chamber and a source of liquid-supply therefor, ot' a discharge-port in communication with said heating-chamber and a feeding-chamber in communication with said heating-chamber having oppositely-disposed bafiies to trap the feed liquid and prevent the escape of the liquid from the heating-chamber except through its discharge-port.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
